FLEXIBLE CONDUCTING-CORD FOR TELEPHONES.

SPECIFICATION forming part of Letters Patent No. 232,908, dated October5, 1880.

Application filed June 29, 1880.

To all whom it may concern Be it known that l, FRANK SHAW, of the cityand State of New York, haveinvented an Improvement in FlexibleConductors for Telephones, of which the following is a specification.

With telephone-instruments it is usual to employ two conductors that arecovered with fibrous material so as to insulate the same, and these twoconductors are within one cord or covering, except that they are allowedto project at the end portions of the cord, so as to be entered into theclamping-holes of the bindingposts 011 the telephone. These conductorsare liable to be injured and become separated or broken in consequenceof careless handling of the telephoneinstrument, and this risk is i11-creased if the telephone-instrument slips out of the hand or rolls fromthe table and .falls, the fall being arrested by the flexible conductor.

My present invention is for the purpose of preventing injury to theflexible conductors near the ends where they unite with the tele phone.This object is accomplished by making the separate conductors of alength sutflciently to pass around the body of the telephone in oppositedirections and leading the single colt ductors in such a manner as toconfine the double part of the conductor near the side of the tel ephone-instrument. This retains the con ductor in its proper position tothe instrument; it prevents any angle or sudden bend being formed inthesingle parts of the conductor; it takes all strain in handling, or, ifthe instrument drops upon loops that are kept of the proper shape by theround body of the telephone-instrument, it insures elasticity andflexibility at the junction of the conductors with the instrument,because such conductors yield freely at the end portion of the doublecord and the contiguous portions of the single cord, and there are nosharp angles or corners around which the parts become bent; hence thereis nothing that can tend to accidentally injure (No model.)

the conductors, and the freedom of movement is not in any respectabridged.

In the drawings, Figure 1 is a side View of the telephone-instrumentwith the improved conductors connected therewith. Fig. 2 is a partialelevation at right angles to Fig. l, and Fi 3 is a separate View of theconductors near one end.

The conductors are of usual construction, except that the separate endsI) are of a length sutflcient to extend around the body of the telephoneabout one and a half times, and at the ends are metallic tips 0, thatare adapted to be clamped in the binding-posts e of the telephone D.

In connecting the flexible conductors to the telephone the fork at theend of the single part of the conductors is placed against the side ofthe telephone near one end thereof. The two parts of the flexible conductor are passed around the telephone in opposite directions, and crosseach other and also cross the single part of the conductors and pass ateach side thereof up to the binding-posts, so that the single portions aof the conducting-cord are confined by the bifurcated portion but theparts are free to yield as the telephone is handled, and the risk of theflexible conductor becoming injured in handling is reduced to a minimum.

I claim as my invention- The improvementherein specified in connectingflexible conductors to telephones, consist ing in passing the singleflexible insulated conductors around a portion of the telephone,crossing said two wire conductors near the double part of theconductors, and securing the same to the binding-screws, so as to retainthe parts in their proper position and prevent injury to the same,substantially as set forth.
